Patent number: 11942495Abstract: A semiconductor device includes a semiconductor chip, a circuit board, a heat releasing plate, an adhesive member, and a conductive member. The circuit board transmits a signal of the semiconductor chip. The heat releasing plate has the semiconductor chip disposed thereon, and has an opening in a region on the outer side of a semiconductor chip placement region that is a region in which the semiconductor chip is disposed. The adhesive member is disposed in a region on the outer side of the opening on a different surface of the heat releasing plate from the surface on which the semiconductor chip is disposed, and bonds the circuit board and the heat releasing plate to each other. The conductive member connects the semiconductor chip and the circuit board to each other via the opening.Type: GrantFiled: June 21, 2019Date of Patent: March 26, 2024Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventors: Daisuke Chino, Hiroyuki Shigeta, Shigekazu Ishii, Koyo Hosokawa, Hirohisa Yasukawa, Mitsuhito Kanatake, Kosuke Hareyama, Yutaka Ootaki, Kiyohisa Sakai, Atsushi Tsukada, Hirotaka Kobayashi, Ninao Sato, Yuki Yamane

Patent number: 8166800Abstract: A gas concentration detection apparatus and system including a gas sensor. Voltage Vd generated across detection resistor Rd through which pump current Ip flows is differentially amplified by OP1, and offset voltage Vofs is superposed thereon to obtain a detection voltage Vout. The amplification factor applied to the differential amplification of the voltage Vd is changed by turning switch SW3 on and off. When switch SW2 is turned on, the input terminal potentials of the operational amplifier OP1 are equalized, so that voltage Vofs is output as the detection voltage Vout. The detection voltage Vout contains an error attributable to the electronic components which form the circuit. The detection voltage Vout containing the error when SW2 is turned on is acquired as a correction voltage for each amplification factor, and is used for correction at the time of detection of the concentration so as to cancel the error.Type: GrantFiled: August 27, 2009Date of Patent: May 1, 2012Assignee: NGK Spark Plug Co., Ltd.Inventors: Norikazu Ieda, Yoshinori Inoue, Hiroyuki Tsukada, Masahiro Tanaka

Patent number: 5978922Abstract: A computer system having a hibernation-type resume function which is performed by using an HDD. Provided on the hard disk of the HDD are storage area for storing ordinary data. Also provided on the hard disk is a resume storage area which is large enough to save resume data required to perform a resume operation. The resume storage area is controlled by a BIOS provided for performing the resume operation, not by the operating system (OS) of the computer system. The BIOS accesses the resume storage area when the power supply to the system is switched off, thereby saving the resume data in a resume data memory.Type: GrantFiled: September 16, 1996Date of Patent: November 2, 1999Assignee: Kabushiki Kaisha ToshibaInventors: Makoto Arai, Shigenobu Sato, Hideaki Muraya, Keiichi Kato, Hiroyuki Tsukada

Patent number: 5963738Abstract: When a BIOS driver call request is generated in an environment of an OS operating in a protect mode, an IN or OUT instruction is executed to cause an I/O trap SMI generator to generate an I/O trap SMI. The mode of a CPU is switched from the protect mode to an SMM in accordance with the I/O trap SMI. In the SMM, the BIOS driver is executed. When the process of the BIOS driver is completed, the mode of the CPU is returned from the SMM to the protect mode, thereby shifting control to the OS. The BIOS can be directly called in the protect mode without building a routine for switching the CPU operating mode in the OS or application program operating in the protect mode.Type: GrantFiled: January 27, 1997Date of Patent: October 5, 1999Assignee: Kabushiki Kaisha ToshibaInventors: Masayo Yamaki, Hiroyuki Tsukada

Patent number: 5442525Abstract: In a vehicle lamp, a lamp bulb assembly is fixed to a reflector disposed inside a housing, and current-feeding terminals extend from a base of the lamp bulb assembly and rigidly connected to a connector. There is provided a sealing member to resiliently seal a small clearance necessarily taking place between the base and connector. When the connector is fitted onto the terminals, the sealing member is resiliently deformed to cover the small clearance. Since this covering is kept, exposed portions, in the clearance, of the terminals are sealed from outside.Type: GrantFiled: December 28, 1993Date of Patent: August 15, 1995Assignee: Ichikoh Industries, Ltd.Inventor: Hiroyuki Tsukada

Patent number: 5390088Abstract: A vehicle lamp device includes a tiltable reflector mounted in a housing; a back opening formed in a back wall of the housing; a rubber cover for sealing a gap between the back wall and a back portion of the reflector; a cylindrical portion surrounding the back opening formed on the housing back wall; a cylindrical supporting wall formed on the back wall, the supporting wall being spaced outside the cylindrical portion surrounding the back opening and extends backward; an annular groove formed between the back-opening-surrounding portion and the supporting wall; a set ring member having a flat set face, for pressing the rubber cover to the housing back wall from behind; an inward-jutting projection formed on the supporting wall, for supporting the set ring member; a peripheral portion of the rubber cover provided with a horizontally-extending cylindrical portion to be inserted into the annular groove and a to-be-sandwiched potion perpendicular to the to-be-inserted portion of the rubber cover; and an inward-eType: GrantFiled: December 16, 1993Date of Patent: February 14, 1995Assignee: Ichikoh Industries, Ltd.Inventor: Hiroyuki Tsukada

Patent number: 5072348Abstract: In a vehicle lamp comprising a housing having a reflector formed integrally therewith, a bulb holder fitted in the rear opening of the housing, a lamp bulb detachably installed in the bulb holder, and a cap covering the rear opening of the housing and the connection of the lead wires of the lamp bulb, the provision of engaging parts for attachment of the cap on the bulb holder negates the need for engaging members on the housing. Thus, no undercut has to be formed in the housing, which facilitates the molding of the housing. Also, the heat radiator provided on the bulb holder reduces the difference in temperature between the lamp chamber and the outside of the vehicle lamp, thereby preventing condensation from taking place inside the vehicle lamp and also allowing the design of a more compact lamp chamber, and in turn, a smaller vehicle lamp volume.Type: GrantFiled: May 7, 1991Date of Patent: December 10, 1991Assignee: Ichikoh Industries, Ltd.Inventor: Hiroyuki Tsukada
